My Church needed a wi-fi hotspot so I proceeded in getting an Airport Extreme (AE). They currently have a Cisco router the furnishes their internet (not wirelessly). Here is my problem. I removed the Cisco router and plugged up the Airport Extreme and I get nothing, just an Amber light on it. Thinking the problem is on their ISP side, I plug the WAN ethernet directly into a computer and it works fine. Spent a few hours on the phone with their ISP doing some troubleshooting to no avail. decided to plug back up the orginal router and then use an ethernet cable to plug into the extreme from the cicso router. That seems to work fine but I would like to get rid of the Cicso router. Am I missing something? Why won't the AE work? I can assure you that it's not a problem with the AE. Any ideas?
